  • 본 연구는 온톨로지를 기반으로 접근점을 제어하기 위해, 미국 작가 마크 트웨인을 대상으로 인물과 이름간의 다양한 관계와 특질을 RDF/OWL의 공리정의를 통해 인명접근점제어 온톨로지를 기술하였다. 적용된 공리정의는 인물 이름클래스 간 서로 소 공리정의, 객체속성의 정의역 치역 공리 정의, 인물 이름클래스의 객체속성 값 출현횟수 제약 공리정의, 인물과 이름 개체 간 역함수 관계 공리정의, 인스턴스와 리터럴 간 데이터속성 공리정의 등이다. 그 결과 온톨로지 기반에서 전거와 표목의 개념을 배제하고 모든 표현형식을 대등하게 다룬 대등형접근점이 기존의 제어기능을 수용할 수 있음을 확인하였고, 다양한 공리정의로 보다 강화된 표현력으로 공유성과 유일성이 광역적으로 확보된 인명접근점제어 온톨로지를 기술할 수 있었다.

  • 정인교는 그의 최근 논문에서 논리적 귀결 관계에 의해 논리 상항의 의미를 정의함에 있어 통상적인 도입 규칙과 제거 규칙에 의거하는 포퍼의 접근법과, 도입 규칙에만 의존하는 정당화주의적 접근법, 그리고 제거 규칙에만 의존하는 실용주의적 접근법을 구분한 바 있다. 이 글에서는 연언과 선언의 연결어의 경우에는 그 세 가지가 동등하다는 것을, 그리고 조건과 부정의 연결어의 경우에는 제거 규칙에 의거하는 실용주의적 접근법과 포퍼의 접근법이 대등하다는 것을, 타르스키가 처음 확립한 논리적 귀결에 관한 공리적 체계에 의존하여 보일 것이다.

  • When we use various multimedia programs such as 3D-game, visual conference, dial-pad phone by internet service, we make use of headset generally. As internet system is magnified more and more, a demand of headset will be increasing continuously. Because microphone was fixed by headset, it has many inconveniences for using headset. For these reasons, new concept headset is needed nowadays. Main idea of development of headset is very the automatic operation system of microphone. There are many process variables in appling new technology to the conventional headset. They can be solved by using axiomatic approach method which is very useful design method for designing new products. Its main character is scientific and analytical. The goal of this research is to design and manufacture a new headset model with axiomatic design method. In this paper, a new concept headset was presented by mapping the relation between functional requirements and design parameters.

  • DVD(Digital Versatile Disk) is the data storage media devised to make high storage density and high speed data input/output possible. For example, a whole length movie can be stored in a disk as large as a CD(Compact Disk). Therefore higher rotational speed and better accuracy in optical pick-up are required compared with the existing optical storage device. Without these operational functional requirements being satisfied DVD will lose its place as the high capacity storage device. This paper evaluated whether the currently developed DVD satisfies the requirements and provides improved methods with the Axiomatic Approach which is superb in evaluating and designing newly concepted designs.

  • In order to execute the major role as the high density large capacity data storage device, which is one of the major characteristics of DVD(Digital Versatile Disk), there must be a method to effectively absorb the external impact or internal vibration. The DVD which has been developed until now tries to control two different types of vibrations, using only one absorber. But this goes against the independence Axiom of Axiomatic Approach which makes the design to be coupled. And in fat most of the malfunctions occurring during DVD data input/output is due to impact or vibration. Therefore in this paper, the vibration absorption system and operation reliability of DVD will be evaluated with the Axiomatic Approach and plans and feasibility to design an improved vibration absorption system will be provided also based on the Axiomatic Approach.

  • Today, one of the most important objective in automobile development is to reduce the weight of automobile . The eventual depletion of petroleum and environmental regulations brought considerable emphasis to this area on increasing fuel efficiency. Conventional intake air-fuel system is very heavy because it is composed of numerous parts. The bulky size caused increase in the amount of metal being used to build automobile chassis and this became a serious weight problem. The size also caused difficulties in optimization of fuel supply system which in turn decreased engine efficiency. Currently , there are efforts to integrate several intake system modules into one. The purpose of this paper is to evaluate the directions of such development.

  • Paraglider has been used for a good air sports instrument by many people in the world though its short history. And manufacturers have improved it continuously. It has the great growth from the first model like parachute to the latest model that has the extreme speed, but we can improve it in more parts. In this paper, we will show the method which can improve its performance by using Axiomatic Approach.

  • CD-ROM drive is improved in rotation speed up to 10,000 rpm. But Vibration and Noise are also increased simultaneously more and more. So many attempts are tried to reduce the unexpected effects. Most attempts are not enough to cover the increasement of Noise and Vibration. Merely availed tries are accumulated in many part and it makes the structure complicated. The Axiomatic approach could arrange the order of design and estimate the optimum design in good oder. In Axiomatic Approach, the composition is divided by Customer Requirement, Functional Requirement, Design Parameter and Design Matrix in large portion. This method also could show more effective way to design before making a prototype.

  • As the rotational speed of optical disk drive is increasing nowadays, the reliability to vibration and shock becomes more important. For this, various of rubber vibration isolators are being developed by varying the shape and hardness. But it is difficult for the hardness of common used rubber to be lowered below Duro 30 degrees, and because of the shape complexity of rubber vibration isolator there are difficulties of analysis. Microcellular foamed vibration isolator has various cell densities and cell sizes, so it can vary the stiffness and damping coefficient. In addition, its hardness can be lowered below Duro 30 degrees. Axiomatic Approach is very useful design method for designing new product or new process. Axiomatic Approach's character is scientific and analytical method. In this paper, developing process of microcellular foamed vibration isolator for DVD is presented with Axiomatic Approach.
